The FRACTUREVISION proppant-delivered fracture evaluation service enables precise fracture evaluation to be performed efficiently and safely throughout the life of the well. The service is made possible?by our unique CARBONRT inert tracer technology which detects proppant placement and provides a direct measurement of propped fracture height.
Enhance fracture design based on directly measured propped fracture height
By directly measuring proppant location and propped fracture height, our services provide you with more accurate information to enhance your fracture designs and enable you to better understand near-wellbore conductivity.
Unlike far-field microseismic and tilt mapping or near-wellbore temperature and sonic logs, our technology enables the direct measurement of proppant location and propped fracture height, reducing uncertainties.
Precise fracture geometry modeling
The FRACTUREVISION fracture evaluation service can be used to accurately measure propped fracture height, determine propped fracture length and verify whether all zones were stimulated as planned. The service also enables you to develop an understanding of duning effects that can have a negative impact on proppant placement and reservoir recovery.
Propped fracture height measurements can then be used to calibrate fracture models and optimize treatments of offset wells. The propped fracture height and approximations for fracture width allow the calculation of fracture length using the mass balance technique.
Propped fracture height measurements are particularly important where there are water bearing zones above the target formation. The propped fracture height can help to avoid the water bearing zones and any other hazards by altering the perforation spacing, as well as the amount of fluid and proppant pumped during the treatment.
Understand near-wellbore connectivity to avoid overflushing
Over flushing at the end of a stage and proppant flowback can lead to loss of near-wellbore connectivity as well as reduced conductivity, in turn reducing production and EUR.
The FRACTUREVISION service enables you to identify over- flushing and to estimate near-wellbore conductivity, which allows the correlation of production to different stage intervals and perforations.
The service also identifies the source of any proppant flowback, and near-wellbore connectivity measurements which can be used to indicate characteristics of an area or the formation to inform the optimization of fracture design.
Improve completion efficiency with optimal fracture and well spacing
By identifying the optimal stage, perforation and well spacing, our service helps you to improve completion efficiency and optimize field development.
The optimization of your fracture, stage and well spacing early in your field development program can reduce the number of wells required and substantially reduce the cost to effectively exploit the full potential of your reservoir.
The precise measurements obtained using our service improves the accuracy of stimulated reservoir volume (SRV) and EUR calculations, which helps you to make more informed development decisions.
Improve perforation efficiency
Our service can be used to evaluate how many perforations have taken proppant and have been successfully stimulated in horizontal wells. By varying the spacing and number of perforation clusters in each interval, you can evaluate perforation efficiency and make adjustments to optimize spacing.
Identify optimal stage spacing
In both vertical and horizontal wells, our proppant-delivered fracture evaluation service can be used to pinpoint propped stage intervals to identify which zones and intervals have been stimulated as planned. This information can be used to identify optimal stage spacing and any potential zones for re-stimulation.
Optimize well spacing
Propped fracture half-length can be determined by detecting fracture hits on offset wells from
a well that has been treated with CARBONRT technology. The spacing of subsequent wells in the program can then be adjusted until the optimal spacing between wells has been reached.
Diversion verification
Until now the success of expensive diversion operations can only be evaluated several years into the productive life of the well or by using radioactive-based technologies. With the FRACTUREVISION service you can now simply alternate the use of the divertor on stages, and then measure the number of perforations that have taken proppant in each stage to immediately verify the success of diversion operations.
Calibrate your propped fracture network and SRV models
The integration of proppant placement measurements obtained using our service, combined with diagnostic technologies such as microseismic, distributed temperature sensing, distributed acoustic sensing and production logs creates an integrated solution to calibrate your fracture network and SRV models. The model calibration enables you to calculate the propped fracture network and propped SRV.
Calibrated models give you a more accurate forecast of EUR compared to only microseismic evaluation that just provides information on where the formation fractured, rather than detecting where the proppant has been placed and the fracture propped. As a result, microseismic solutions only model discrete fracture networks and SRV, which only tell you what fractures and volumes have fluid.
Efficiently and safely evaluate your fractures for the life of the well
Our FRACTUREVISION proppant-delivered fracture evaluation services use CARBONRT inert tracer technology, which is highly efficient, completely safe, and licensed for use worldwide.
Evaluate ceramic and sand completed wells
The FRACTUREVISION service can be used to evaluate wells completed with sand or ceramic.
In wells propped with any CARBO ceramic proppant, the inert tracer is manufactured into every proppant grain and forms an integral part of the matrix of the proppant material so it cannot be dissolved or washed away. CARBONRT tracer technology is field proven and has been used to evaluate fractures in unconventional plays worldwide.
For sand completed horizontal wells, a new, easily detectable inert tracer technology is blended at an engineered ratio with sand to ensure that the traceable proppant can be effectively detected within the non-traceable sand.
Operational and environmental advantages
Proppant enhanced with CARBONRT technology is pumped like any other and requires no special equipment, handling, training, permits or certifications, and delivers significant cost savings over other evaluation methods. The technology is also safer than radioactive tracers, with no need for special handling considerations.
No impact on proppant performance or physical properties
The tracer is manufactured into the proppant matrix and represents only 0.4% of the proppant chemistry, so its physical properties are almost identical and its downhole performance unaffected.
Detectable for the life of the well
A unique feature of CARBONRT technology is an inert, permanently traceable material. Unlike radioactive tracers, there are no shelf life or half-life issues, so evaluation can be performed efficiently at any time during the life of the well.
Proppant enhanced with CARBONRT technology has a high neutron capture cross section. As the tracer absorbs neutrons from the neutron tool, it emits gamma rays altering the log response of a standard neutron log. The precise location of the proppant is detected by the lack of gamma rays and the unique spectral signature of the tracer. Our CARBO fracture technology specialists then convert the log readings to provide you with measurements.
